You certainly present a thorough argument, thanks for that. I guess for now I just make do with what I’ve got and build it up to a proper server over time. Appreciate all your efforts

Well that's discouraging as I was certainly led to believe that my setup was rather typical. So my only option now is to do a full manual mirror backup of each drive?

They’re all external USB drives- my HP chassis had 8x USB ports, 6 rear and 2 front

You're right- sloppy word choice

I stand corrected...but I couldn't see this in my BIOS settings. Seems I need to spend a little more time finding my way around it..... Thx and will let you know if anything changes

Hi All - total newbie here and I know there have been plenty of posts already on this topic but I've done what I've read so far to no avail. Started using Unraid Pro about 2 months ago (v 6.10.3) on a 4-5 year old HP PC I had laying around. I have 1x 18Tb, 2x 14Tb, and 2x 3Tb Western Digital drives with another 18Tb as my parity backup. I managed to get the array all up and running, used Midnight Commander and Crusader and Plex docker for weeks with no problems. But when I try to do my initial parity scan, it keeps freezing at 11.8% and I need to hard reboot manually. I did a memtest for 24hrs with no errors, I see no XMP options in my BIOS, and don't seem to have any drives set to IDE as per some of the other posts I've read. I'm not entirely certain which log/diagnostics files are required - I've attached the tower-diagnostics zip but if more info is needed am glad to provide it if someone lets me know what. Thx in advance R tower-diagnostics-20220801-2103.zip
